4.1.5.4.2. General Purpose Address Space

General purpose address space is for general purpose use, and it supports multiple address regions. The regions can only be configured via CSR accesses and must be configured by software at boot up. They can be mapped to either normal memory (DMI) or a peripheral device (DII). The size of these regions must be a power of 2 within the range of 4 KB and 32 TB (achieved via interleaving). The base address configured must be aligned to the size of the region.

The default address regions for Agilex™ 5 are defined in the following table.

Note: Not all the address space is mapped to memory or peripherals. Refer to Address Map for more details.
